IMPORTANT Once the venting system is installed, attach the “Disconnected Vent” warning sticker to a visible area of the plenum near the vent pipe. See Figure 23. The warning sticker is provided in the bag assembly. Order kit 66W04 for additional stickers. WARNING Asphyxiation hazard. The exhaust vent for this furnace must be securely connected to the furnace flue transitiion at all times. Vent Connection Figure 23 Use self drilling sheet metal screws or a mechanical fastener to firmly secure the vent pipe to the round collar of the flue transition. If self drilling screws are used to attach the vent pipe, it is recommended that three be used. Drive one self drilling screw through the front and one through each side of the vent pipe and collar. See Figure 23. Install the first vent connector elbow at a minimum of six inches (152 mm) from the furnace vent outlet. See Figure 23. Venting Using a Masonry Chimney The following additional requirements apply when a lined masonry chimney is used to vent this furnace. Masonry chimneys used to vent Category I central furnaces must be either tile lined or lined with a listed metal lining system or dedicated gas vent. Unlined masonry chimneys are prohibited. See Figures 24 and 25 for common venting. A chimney with one or more sides exposed to the outside of the structure is considered to be an exterior chimney. An exterior masonry chimney that is not tile lined must be lined with B1 vent or a listed insulated flexible metal vent. An exterior tile lined chimney that is sealed and capped may be lined with a listed uninsulated flexible metal vent. If the existing chimney will not accommodate a listed metal liner, either the chimney must be rebuilt to accommodate one of these liners or an alternate approved venting method must be found. Insulation for the flexible vent pipe must be an encapsulated fiberglass sleeve recommended by the flexible vent pipe manufacturer. See Figure 24. Common Venting Using Metal Lined Masonry Chimney NOTE 1: Refer to the provided venting tables for installations. Refer to the capacity requirements shown in the provided venting tables. Figure 24 506526-01 Issue 1031 Page 15 of 39 Common Venting Using Tile Lined Interior Masonry Chimney and Combined Vent Connector NOTE: Refer to provided venting tables for installations. NOTE: The chimney must be properly sized per provided venting tables or lined with listed metal lining system. Common Venting Using Tile Lined Interior Masonry Chimney and Combined Vent Connector NOTE: Refer to provided venting tables for installations. NOTE: The chimney must be properly sized per provided venting tables or lined with listed metal lining system. Figure 25 DO NOT insulate the space between the liner and the chimney wall with puffed mica or any other loose granular insulating material. IMPORTANT SINGLE appliance venting of a fan assisted furnace into a tile lined masonry chimney (interior or outside wall) is prohibited. The chimney must first be lined with either type B1 vent or an insulated single wall flexible vent lining system which has been sized according to the provided venting tables and the vent pipe manufacturer’s instructions. A fan assisted furnace may be commonly vented into an existing lined masonry chimney if the following conditions are met: • The chimney is currently serving at least one drafthood equipped appliance. • The vent connectors and chimney are sized according to the provided venting tables. If type B1 double wall vent is used inside a chimney, no other appliance can be vented into the chimney. The outer wall of type B1 vent pipe must not be exposed to flue products. A type B1 vent or masonry chimney liner shall terminate above the roof surface with a listed cap or a’iisted roof assembly according to the terms of their respective listings and the vent manufacturer’s instructions. When inspection reveals that an existing chimney is not safe for the intended purpose, it shall be rebuilt to conform to nationally recognized standards, lined or relined with suitable materials, or replaced with a gas vent or chimney suitable for venting. The chimney passageway must be checked periodically to ensure that it is clear and free of obstructions. Do not install a manual damper, barometric draft regulator, or flue restrictor between the furnace and the chimney. Never connect a Category I appliance to a chimney that is servicing a solid fuel appliance. If a fireplace chimney flue is used to vent this appliance, the fireplace opening must be permanently sealed. A type B or listed chimney lining system that passes through an unused masonry chimney flue is not considered to be exposed to the outdoors. General Venting Requirements Vent all furnaces according to these instructions: 1. Vent diameter recommendations and maximum allowable piping runs are found in the provided venting tables. 2. In no case should the vent or vent connector diameter be less than the diameter specified in the provided venting tabl...
